Quizplus · Accepted Answer

The respiratory pump refers to the movement of blood from the abdominal veins into the thoracic veins that occurs during breathing. This movement is due to the pressure changes that occur in the thoracic cavity during respiration, which create a vacuum that pulls blood upward into the chest. The skeletal muscle pump refers to the movement of blood in the limbs, which is aided by the contraction of skeletal muscles. Diaphragmatic breathing refers to breathing that involves the contraction of the diaphragm muscle. Valvular insufficiency refers to a condition where the valves in veins do not function properly, leading to backward flow of blood. Blood colloid osmotic pressure refers to the pressure that opposes outward flow of water from blood vessels due to the presence of large molecules, such as proteins, in the blood.
